1206TD-1.5A from prosemi, in a 1206. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | One terminal of the two-terminal 1206TD-1.5A time-delay chip fuse (1.50 A rating, 0.23 ohm typical cold resistance); the fuse is not polarized and the datasheet gives no pin names. |
| 2 | 2 | passive | Second terminal of the two-terminal 1206TD-1.5A time-delay chip fuse (1.50 A rating, 0.23 ohm typical cold resistance); the fuse is not polarized and the datasheet gives no pin names. |
